p Figure 8 is a View 'similar to Figure 4 of the gate shown in Figure 7;and

yFigure 9 is an enlar ed fragmental view of the gate shown in shown insection to emphasize certain structural features,

The form of gate illustrated in lFigures 1 to 5 is composed of aplurality `of vertical tubes 10 connected4 by hinge members 11.

of any with in anl enclosure when in c osed position and of uncoveringvigure 7, parts being P lone at the bottom and one in the mi dle.

Each'hinge member comprises a yoke 12, a pair of lugs 13extendingoutwardly therefrom and a slmilar but oppositely extending pairof lugs 14,:A wider space isprovided etween the lugs 13 than between thelugs 14.111 order'to permitthe lugsfglt on the adjacent hmge member toextend therebeltween. Apertures 15 are 'gprovided in lugs 13 and slmilarapertures lf3-in lugs 14,.-

With adjacent hinge members in assembled relation., the-apertures 15 and'16 are-,in 'vertical ahgnment sowas to ,receive-'one of the4 tubes 10.'Each hinge member is secured. to

Va .tube as by means of-pin's y17 extending.V

through lu'gs 14, vHowever,the hinge meml bers are not pinned to`thejtubes lthrough the .lugs 13h, they bein'g freeto `iturn at thesepoints. In this'manner eachfctube isvhinged to its adjacent tubefwithg.the hinges maintained in position by the .pins 17.

Each tube 1Q extends-upwardly into` a hanger, the `hangers for t elintermediate tubes being designated"*18. 'As clearly shown for one ofthe intermediate tubes inr the top of the jboss 2O to form a verticalbearing for the tube. The frame of the hanger is formed with a yokeportion 24 and two sides 25 and 26, theside 26 lsupporting the boss 20.A roller 27 is supported between thesides of the hanger as by a pivotpin 28, the pivot in in turn being maintained in position y a Apin 29.Thesey roll ers ride on the track 30. As shown in Figure 2 in apassenger type car, the track 30 extends across `the front, bends at thefront left-hand Vcorner and continues along the side of the car to therear thereof. The track may be supported in any suitable manf ner, as bystuds 31 extending from plates 32 secured tothe car at intervals alongthe ath just described. It is to be understoodA that, if desired,suitable reinforcements may be arrangedon the car to facilitate thesupport of the track. This track acts both as a support and a guide forthe gate.

The construction of the end hangers r19 is' slightly modified, one ofthe end hangers 'being illustrated in Figure 3., The con-V struction ofthe top of the hanger is the same as above described .for one of the1nvtermediate hangers. ,Atf the bottom how-- ever, a portion 33 ofthe'hanger extends upwardly from the boss 34. 'An additionall roller 35is sup ortedl bet-ween'the side 36 and portion 33 y a pin. 37. Forlightness ofl construction, the lframes of the interme diate and endhangers are preferably of. channel shape, as indicated by the brokenaway portions infFiguresB and 4 and in Fi re 5.

wardly into a channel 3 8. .This channel acts as a guide for the bottomof the 'gate, the

channel'being of the same contour as the overhead track 30. Flanges 40are formed on the sides of the channel, the channel be#- 'ing secured'tothe floor 41 of the car as by .screws 42 extending lthrough the.channel.

' -A plurality of apertures 43 areformed in tion of the gate. A false.panel 45 is arthe bottom lof the channel, coincidin =aper' 'tures' 44bein formed in the 'car allow' dirt to all-through. Otherwise suflicientdirt or-other matter might accumulate in the channel to prevent theproper operaranged in the car parallel with the left-hand.` sidethereof. The panel may .also extend a short distance to the right vatthe front of the car, as illustrated. Theportions ofthe track 30andchannel 38 at the left'front and side of the car extend between the,panel and the car. I

The lugs 14 of the rightfhand hinge mem ber in each row are connected bya'bumper plate 46. Bumpers 47 are secured to the side of the car anddisposed in .the paths of these bumper plates. Similarl the lugs 13 ofthe left-hand hinge mem ers in 'each row are connected by a lbumperplate 48. Bumpers are secured Ato the car at the rear in the paths ofthese plates;

.It isto be understood that, if desired, the

track 'and'rollers may Vbe 'arranged'at ,theVA bottom 4of the gate withthe channel disposed.

at the top. It is to be further understood `that the gate .may be poweror manually op-` erated, no power means being shown for convenience ofdescription.

. With the-gate arranged for manual o eiation .and in closed "positionas illustrate in Figure 1, to open the -gate the yoperator'may grasp oneof the tubes 10, lpulling the gate to the left. The left-hand tube 10 isillustrated in Figure 1 as substantially on the vbend of the track. '1Uon movement of the gate to the left, the r'o lers 27 and 35y of the leftend lhanger are' guidedby the track around the corner, 'Figure 5-illustrating the different positions which Vthe various parts mayassume'.v The left len'd hanger 19 pivots on a vertical axis as itsrollers turn the cor-- he bottoms of the tubes 10 'extend downoor, to

ner. lAs previously explained, the left end tube l0 -is free to turn in`the lugs 13 of the left end hinge members and in the hanger but theadjacent or next tube to the right is secured to the lugs 14 of thesehinge mem bers. The movement of the left end tube around -the corner ispermitted by the plvoting of the second tube within the apertures inlugs 13 of the adjacent or second hinge members and hanger. Thesuccessive tubes, hangers and. hinges act in a similar 'manner duringthe continued movement of the gate -around the corner. The track 30 andchannel 38 guide the gate` between the side oflthe car and the panel445. Upon the gate reachingits open position, it is stopped.

y the lengagement of the bumper plates 48 and bumpers 50. It is to beunderstood-that the bumpers are made of material suitable toabsorbanyshocks. The gate is illustrated in its open'position inlFigure 2. Itis `.to be noted that the right-hand end' tube 10^ex tends slightly `outfrom l behind the pan'el with the gate in open position. The gate may beclosed by reverse operation, the operator grasping the `right-hand tube,pulling the ate to the-right. As the gate reaches its c o'sed position,it is stopped in a similar manner by the engagement of bumper plates 46and bumpers 47,. The rollers 35 prevent loo' movement.. Should the carbe too deep, the

bumpers 50 may be arranged on a properly located partition between theside of. the car and the false panel. It is to'be understood that thegate is equally adapted for the cars which are controlled by thepassengers them` selves.v V l l It has beenfound in actual .practicethat the gate operates with very little noise. Due to the fact that thetubes 10 aremaintained separated at all times, the danger of injury tothe operator or passengers such as pinch- *ing of the hands or fingersis substantially eliminated., Furthermore due to the. fact that the gateuncovers the Whole of the pas` sageway into the car when opened, thetraffic ma be handled'with maxnnum despatch.

In. igure 6, the gate is illustrated as arranged on a freight type ofelevator car.'

The structuralI details of the gate are substantially the same'as thoseabove described. ,The track 55, however, is" mounted on the .A

outside of the car, being secured in a manner similar to that abovedescribed by studs 31 and plates 32. Thus with the kgate mounted lon thetrack, the sides 26 and 36 of the hangers are on the outside. Thechannel .56 is illustrated at the side of the car with the flangesremoved in order that'the gate may be 'mounted outside the car withoutundue consumption of the hatchway space.v The channel may be secured tothe side of the car by studs and .plates in the manner emoutwardly. Asillustrated cept on the turn,

ployed to secure the track. Also the outer flange of theA channel infront ofthe car may be omitted, as illustrated.v Bum ers 57 and 58similar to those described or the passenger car may be providedifdesired.-

The gate is operated in the lsame 'manner as described for the passengertype car, the gate being illustrated in its open position. It is to benoted that, in this position, the right-hand end tube and bracket. aretothe left of the side of the cary thus presenting an opening of the samewidth as the inside of theear. y

Referring to Figures 7 .and 9, the gate therein illustrated for apassenger type of car, is formed of upright channel members 60 arrangedwith their flan s extending in igure 9, exthe flanges are in abuttingrelation, thus presenting a closed type of gate. hinge members 461arranged in three rows. With the exceptionvof the right-hand hingemembers .of the two lower rows in Figure each hinge member is formed oftwo spaced lugs 62 and a single lug 63 connected by the plate 64. Eachhinge member in each row is secured, as by rivets 65, to one of thechannel members 60. The single lug.63 on each hinge member'extendsbetween the lugs 62 on its adjacent hinge member, being joined by hingepins vextending through apertures 66 provided in the lugs. The hingepins 67 for the two lower rows of hinge membersare formed at theirtopswith ositioning heads 68. The hinge pins 70 or the to row of hingemembers are formed wit lianges 71 at their bottom ends which act assupports for the gate. The hinge pins 70 extend upwardly into thehangers 18 and 19 where they are pivotally secured in the same manner aspreviously described for the tubes 10. Tins 72 are riyete'd or otherwisesecured to the bottoms ofv the channel members 60. These pins extendinto 'thel channel 38 to guide the gate at the bottom. ven the gate isclosed, the right-hand channel member 60 extends partially into achannel 73 secured to the side of the car. The lefthand channel member60 extends partially .behind the front portion of the false panel 45.lIn this manner the passengers view of vthe hatchway is completely'shut0H. This is of particular advantage in high speed elevator systems asvisual realization of rap- 'left-hand hinge members 61 to engagebumplers 77 are arranged the channel membersuponv occurs beforethe'y'emerge .handle 74 is just to The channel members are )oined byidly passing the successive floors is 'very annoying 'tosome passengers.The right-hand channel 'mem-ber may bel provided" with a. handle`74v tofacilitate the pening and c losy in operation'. v

umper plates 75 join' the"lug's62 of the ers (not shown) when the gateis movedinto openposition. A bumper 7 6vis secured to the car at the tothereof, being disposed:

`in thev path,v ofthe ugf63V of the right-hand hinge member" 61.'"Eherlght-hand hinge members forv themiddle Aand bottomr'ows are formedwith Athe lugs 63 omitted. Bump, y in horizontal alignmen-t with the'`middle and lower-rows of'hinge members to engage the ,outer flange ofthe right-hand channel member.

Upon movement of the gate, the channel members spread apart at the turn.It is 'to be noted,however, that'the reengagement of closing the gatefrom behind the front portion of the false panel 45. Thus in'ury to theoperator or passengers such as mlght result from' catching ythe lingersin between the channel members is prevented.

With the gate in full open position,

panel, presenting substantially a full opening. Thus with 4the closedtype of gate also, traffic may be handled at each 'stop a v minimum oftime. 4

Gates 4constructed in the above describedmanner may be designed'to 'turnvery sharp corners, the sharpness of the turndepending on the dimensionsof the various 'parts employed. In practice-a two and one-halfinchradius 'for the curve at thev corners has been found satisfactory. Y I

As many 'changes `could be made in the above construction and manyapparently widely different embodiments of the invention could be madewithout departing from the scope thereof, it is intended that all mattercontained in the above description or shown in the accom anying drawingsshall be interpreted as "il ustrative and not in a limiting sense.
